    ```
    deleteOrphanAliases();
    function deleteOrphanAliases() {
        var orphanAliases = new GlideRecord('sys_alias');
        orphanAliases.addEncodedQuery("nameSTARTSWITHDevOps-_-");
        orphanAliases.query();
        while(orphanAliases.next()) {
            if (!checkIfAliasHasConnection(orphanAliases.getUniqueValue()))
                orphanAliases.deleteRecord();
        }
    };
    function checkIfAliasHasConnection(sysAliasId) {
        var httpToolConnGR = new GlideRecord("http_connection");
        httpToolConnGR.addEncodedQuery("connection_alias=" + sysAliasId);
        httpToolConnGR.query();
        if (httpToolConnGR.next())
